irregular heartbeat

I am 6 weeks and 3 days with baby number 5.  I've been suffering irregular heartbeats for the last week or so. They're daily and quite a few in a row. I talked to my OB about it and he didn't seem concerned, he prescribed an anti anxiety med!! I explained " these palpitations cause the anxiety, not the other way around'!!! He said well 'it can be hard to tell'!!! Harrumpff!! He also referred me to cardiology, i already take BP and pulse meds routinely. Google is not my friend tonight as I've already diagnosed myself with deadly ventricular tachycardia ( I'm a nurse, which doesn't help) anyone else with nasty palpitations? Needing reassurance right now 😢
